ASH-CAN ATTACHMENT.

To all whom it may concern:

Be it known that I, BENJAMIN F. HARD- ING, a citizen of the UnitedStates, and residing at Milton, in the county of Norfolk and State ofMassachusetts, have invented an Improvement in Ash-Can Attachments, ofwhich the following is a specification.

This invention relates to ash-c1111 attachments, and has for its objectto construct an attachment adapted to cover the top of an ash-can havingan entrance at the side through which the ashes are passed to the can,and having means to prevent the dust from passing out through saidentrance; and also having an exit at the side from which a flue-pipeleads, which is adapted to be swung into position in front of thefeeddoor of a furnace or other type of heating apparatus, a largeproportion of the dust which rises being drawn through said fluepipe. Asthe ashes are thrown into the can through the entrance the dust risesover substantially the entire area of the can, and while the flue-pipeis able to carry off a large proportion of the dust yet that whichfollows up along the side wall of the can, more or less remote from theexit, will pass out of the entrance, unless means are provided toprevent it, and herein lies the essential feature of my invention.Herein said entrance is protected above and below and at one end byinwardly extended shields, and the dust which rises and is directedtoward the entrance is caused to strike said shields and is deflectedinward or its progress checked. The entrance is arranged with one of itsends close to the exit so that a shield is not required at said end. Atthe outside of the entrance forwardly extended flanges are or may beprovided which extend entirely around it, to thus increase its depth andthereby aid in preventing dust from passing out.

Figure 1 is a side elevation of an ash-can attachment embodying thisinvention arranged in connection with a portion of a furnace. Fig. 2 isa plan View of the attachment. Fig. 3 is a vertical section 011 line 3-3Fig. 2, looking toward the right. Fig. A is a vertical section on line14E Fig. 2, looking toward the entrance. Fig. 5 1s a perspective view ofthe attachment.

In the drawing 10 represents an ash-can of any suitable constructionupon the top Specification of Letters Patent.

of which my newly devised attachment is adapted to be placed temporarilywhile the can is being filled with ashes.

12 represents an upright cylinder, here shown as of lesser diameter thanthe in ternal diameter of the can, having secured to its outer side nearthe bottom a horizontal flange 13, adapted to rest on the top of thecan, with the lower end of the cylinder extended for a short distancedown into the can to thus prevent displacement of the cylinder withrespect to the can while resting thereon. Said cylinder 12, as hereshown, has a flat top plate 14 by which its upper end is closed. Saidcylinder has in its side wall an opening 15 designed to serve as theentrance through which the ashes are passed to the can. Said entrance isof any suitable dimensions, but it is understood that it will be madelong enough for the easy entrance of a shovel, and high enough to permita shovel filled with ashes to be easily passed therethrough. Saidcylinder also has in its side wall, near one end of the entrance, anopening 16, adapted to serve as an exit for the dust, and from said exita flue-pipe 17 leads, which is attached at one end to the cylinder byengaging aflange 18 around the exit, in any usual manner, the oppositeend of said flue-pipe being adapted to be swung into position in frontand into the feed-door entrance 19 of a furnace 20, or other type ofheating apparatus.

As the ashes are passed through the entrance and dumped into the can thedust rises and a large proportion of the dust passes through the exitand flue-pipe to the furnace. The dust which rises close to the backwall of the can has a tendency to strike the top 14 and some of it isthereby directed toward the entrance, and to prevent the same frompassing out through the entrance a shield 21 is arranged horizontallyacross a segment of the cylinder 12, 011 the inside thereof, at the topof the entrance, beginning at one end of the entrance near the exit 16and extending to a point beyond the other end of the entrance, thusforming a pocket above the entrance, and the dust which rises and whichis deflected toward the entrance by the top plate strikes upon saidshield and is thereby deflected inward or its progress checked.

To prevent the dust which rises close to under side of said shield andis deflected inward or its progress checked.

To prevent the dust which rises at the side wall of the can opposite theexit 16 and which is directed toward the entrance, from passing outthrough the entrance an end shield 23, is arranged at that end of the entrance, which is vertically disposed between the two shields 21 and 22aforesaid, extending inward to the inner edges of said' shields, thusforming a pocket between the several shields and the wall of thecylinder, as shown in Figs. 2 and 4, and the dust which rises and movestoward the entrance strikes said shield and is deflected inward or itsprogress checked. Thus it will be seen that inwardly extended shieldsare arranged about three sides of the entrance, and owing to theproximity of the exit 16 to one end of the entrance, an inwardlyextended shield at such point is deemed unnecessary.

- On the outside of the cylinder around the entrance forwardly extendedflanges are provided, the top flange 24 being arranged in the same planewith the inwardly extended top shield 21; the end flange 25 beingarranged in the same plane with the inwardly extended end shield 23 andthe end shield 26 at the end of the entrance nearest the exit beingarranged in a vertical plane, and the flange 13, serving as the bottomflange in front of the entrance, all of said forwardly extended flanges24, 25 and 26 terminating at their front edges in the vertical plane ofthe outer edge of the flange 13. Thus it will be seen that outwardlyextended flanges are arranged entirely around the entrance.

The relative position and proximity of the exit and entrance to eachother are important in adjusting the attachment on the can, to thegreatest convenience of the operator.

The severalparts of the attachment are or may be made of galvanizedsheet-iron and secured together by ordinary tinsmans joints orotherwise, so as to be quite inexpensive.

In operation the can is located close to the furnace and the flue-pipeleading from the attachment is swung into position in front of thefeed-door and the operator can then easily and quickly remove the ashesfrom the ash-pit of the heating apparatus with a shovel and throwtheminto the can, without being troubled in the least by the dust.

I claim:

The removable ash-can attachment herein described, consisting of acylinder having means at its lower end to engage the top of the can, andhaving a closed top, an oblong entrance in its side extendlng from thecan engaging means to near the closed top,

an exit in its side near one end of the entrance from which a flue-pipeleads, a horizontal inwardly extended shield at the bottom of theentrance, a horizontal inwardly extended shield at the top of theentrance arranged a short distance below the closed top, and a verticalinwardly extended shield at the side of the entrance opposite the exit,extended from the lower to the upper horizontal shield, said shieldsdeflecting and checking the progress of the dust which moves in adirection toward the entrance.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
